What’s The Difference? Diet Coke vs. Coca-Cola Zero

When it comes to Coca-Cola products, people tend to be die-hard fans. Many of us know someone who can’t go a day without a Diet Coke (or two or three). And while Diet Coke has been a leading sugar-free soft drink since it was first released in 1982, it came to light that young adult males shied away from this beverage — identifying diet cola as a woman’s drink. The company’s answer to that predicament came in 2005 — in the form of a shiny black can — with the release of Coca-Cola Zero.

While Diet Coke was created with its own flavor profile and not as a sugar-free version of the original, Coca-Cola Zero aims to taste just like the “real Coke flavor.” Despite their polar opposite advertising campaigns, the contents and nutritional information of the two sugar-free colas is nearly identical. With that information in hand we at Kitchen Daily needed to know: Which of these two artificially-sweetened Coca-Cola beverages actually tastes better? And can you even tell the difference between them?

Before we get to the results of our taste test, here are the facts:

Diet Coke

Motto: Always Great Taste

Nutritional Information: Many say that a can of Diet Coke actually contains somewhere between 1-4 calories, but if a serving size contains fewer than 5 calories a company is not obligated to note it in its nutritional information. Diet Coke’s nutritional information reads 0 Calories, 0g Fat, 70mg Sodium, 0g Total Carbs, 0g Protein.

Nutritional Information: While the label clearly advertises this beverage as a zero calorie cola, we are not entirely certain that its minimal calorie content is simply not required to be noted in the nutritional information. Coca-Cola Zero’s nutritional information reads 0 Calories, 0g Fat, 70mg Sodium, 0g Total Carbs, 0g Protein.

Coca-Cola Zero: “Has more of a sharply sweet aftertaste I associate with diet sodas.” “Tastes more like regular coke, less like fake sweetener.” “Has an odd taste.” “Tastes more like regular.” “Very sweet.”

Overall comments: “That was a lot more difficult than I though it would be.” “Both equally palatable.” A few people said Diet Coke tasted much better … unbeknownst to them, they were actually referring to Coca-Cola Zero.

IN SUMMARY: It is a real toss up. There is not one artificially-sweetened Coca-Cola beverage that outshines the other. So how do people choose between one or the other? It is either a matter of personal taste, or maybe the marketing campaigns will influence their choice.
